"After surviving its star’s red giant phase, Kepler-70b emerged as a small, rocky core of its former self—about the size of Earth. Its surface is hotter than our Sun, soft and molten. The planet is slowly evaporating as it orbits a dim, dying parent star every 4.8 hours."
Kepler-70b is a rocky planet that’s earthlike in composition and size. But earthlikes can range from terrestrial to a rock/gas mix to dense gas only. Snowball planets with a frozen surface and water worlds with an ocean surface are also possible.

Super-Earth System
Super-Earths are two to 10 times more massive than Earth. The TOI 270 system has at least three of them, all closely orbiting a red dwarf. TOI 270 b is likely rocky, but TOI 270 c and d are more massive and probably a mix of gas and rock—more like sub-Neptunes.

Alien Neighbors?
Is there alien life next door? In Alpha Centauri’s system, Proxima b is the nearest exoplanet to Earth. It might be earthlike and even habitable, with a sister planet nearby. But despite its nearness, data readings are tough to parse with three stars in the mix.

Fuzzy Brown Dwarfs
Our exoplanet quest is new, distances are vast, and identifications are fuzzy—with tricksters in the mix. Brown dwarfs can be easily mistaken for exoplanets. These dim, failed stars have too little mass to ignite nuclear fusion but more mass than a planet.

Hypothetical image of Kepler-70b.
Kepler-70b (formerly known as KOI-55.01 and KOI-55 b) is one of two postulated exoplanets orbiting the subdwarf B star Kepler-70.
